Claims

[Scope of utility model registration request]

The back floor plate, the lumbar floor plate, and the leg floor plate are connected to each other in a flexible manner, and the back floor plate is rotatably fixed to the floor plate support frame at an appropriate distance away from the connection point with the lumbar floor plate toward the head. The waist floor plate and the leg floor plate are supported by a second rotation support arm that is connected between the leg floor plate and the floor plate support frame at a position away from the connection point thereof. and supported by the leg floor plate or waist floor plate and a third rotation support arm connected between the floor plate support frame at the connection point or a position close to the connection point,
The first, second, and third rotation support arms are configured to form a parallel movement mechanism when the back floor plate, lumbar floor plate, and leg floor plate form a planar shape, and the first rotation support arm A support mechanism for a floor plate in a floor plate undulating type bed, characterized in that a stopper means is provided for fixing the floor plate at an appropriate angle and making it unrotatable.
